T aZZ whom, it may concern.-

Be it known that we, KARL KOCH and ALEXANDER STELLING, subjects of the King of Prussia, Emperor of Germany, and residents of Hohenlimburg, in the Province of Westphalia, German Empire, have invented a new Article of Manufacture Consisting in Metal Felt, of which the following is an exact specification.

Our invention relates to a new article of manufacture consisting in felt manufactured from metal, which metal felt can be used for different technical purposes. The article consists of Very thin and small metal wires which I 5 are connected to each other in such way that a soft, flexible, and compressible mass arises, which mass has the same structure as felt. The product may be used for various technical purposesfor instance, for tightening 2o fish-plates, especially when the same are exposed to high temperatures, and the like. Chiefiy the metal felt will be employed as an insertion between metal plates or other metal pieces which shall be electrically connected.

The metal felt can be strengthened by the insertion of metal webbing or by surrounding the same with such webbings. Also it can be combined in any other suitable way with other materials used up till nowin electrical engineering.

The new article is represented in the accompanying drawings, in which- Figure 1 shows a piece of metal felt in perspective view. Fig. 2 shows another piece Serial No. 64,191. (Specimens) with a webbin g insertion and a webbing layer on both sides.

a is a metal felt proper, consisting of very thin metal wires. 1) is a metal-webbing insertion. b b are metal webbings between which the metal felt is situated.

Having thus fully described the nature of our said invention, What we desire to secure by Letters Patent of the United States is- 1. A new and useful article of manufacture, consisting in a felt manufactured of very thin metal wires, substantially and for the purpose as set forth.

2. A new and useful article of manufacture consisting in a felt manufactured of very thin metal wires with an insertion of metal webbing, substantially and for the purpose as set forth.

3. Anew and useful article of manufacture, consisting in a felt manufactured of very thin metal wires, with a metal webbing inserted between and surrounding the same, substantially and for the purpose as set forth.

In testimony whereof we have signed our names to this specification in the presence of subscribing witnesses.
